CRIMPING- MACH IN E.

SPECIFICATION forming part of Letters Patent No. 256,475, dated April 18, 1882,

Application filed January 25, 1882.

To all whom it may concern:

Be it known that I, SAMUEL A. GOULD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Crimping-Machines; andIdo hereby declare the following to be a full, clear, and exact description oftheinvention, that will enable others skilled in the art to which it appertains to construct and use the same, reference beinghad to the accompanying drawings, and to letters of reference marked thereon, forming a part of this specification.

This invention relates to that class of crimping-machines that are employed in preparing metallic facings for wash-boards, and is an improvement on Letters Patent- No. 237,515.

This improvement consists more especially of an attachment for throwing the machine proper in and out of gear, and at the same time forcing the prepared facing out from between the dies.

The general construction of the machine proper is the same as that in the patent above referred to, and the description in this case will therefore be confined to the improved attachment.

Figure 1 is an end elevation, showing the position of the mechanism composing the attachment when out of gear; Fig. 2, a view of the same when in gear; Fig. 3, a view of the opposite end of the machine; Fig. 4, a vertical transverse section in the plane 3 3, Fig. 5; Fig. 5, a view of the back side of the machine; Fig. 6, a horizontal section in the plane 6 6, Fig. 5; and Figs. 7 and 8, detached details of construction.

Referring to the drawings, A represents the supporting frame-work, and B the roller or shaft carrying the series of cams C. At that end of the machine illustrated in Figs. 1 and 2 of the drawings, and at the right hand of the operator, is located the vertical shaft B, which has both a lateral and a vertical movement, and has bearings in the brackets a a, attached to the frame-work A. On and near the upper end of the vertical shaft B is placed the collar B provided with the jaws a a. The upper jaw, a is somewhat broader than the lower jaw, and as the lower or inner end of the op- (No model.)

crating-lever B passes by the lower jaw it impinges against the under side of the upper jaw, a when the mechanism is thrown into gear, as shown in Fig. 2 of the drawings.

The contact of the operating-lever B produces a vertical movement of the shaft B, and at the same time releases the lower end of this shaft, which then receives a slight lateral movement in an outward direction from the machine.

proper, brin gin g the lower jaw, u immediately underneath the engaging end of the operating lever B, thereby preventing these parts from becoming disengaged until properly released. The mechanism imparting the lateral movement to the shaft B will be explained further along.

At a point near the lower end of the vertical shaft B is placed the collar B provided with the projecting arm C. Below this point, and onthe same shaft, is the collar C provided with the projecting arm C. These collars are set on the shaft so as to bring the integral projections at about'right angles to each other.

To the outer end of the projection C is pivoted one end of the short connecting-arm C, (more clearly shown in Fig. 6 of the drawings,) the other end being attached to the outer end of the bent shifting-lever D, the opposite end of this shifting-lever branching oft into two parts, forming the yoke a, one branch passing over and the other underneath the clutch-box D, as shown in Fig.8 of the drawings, the two branch ends joining again, and are bolted to the bracket 1), attached to the back side of the frame A, as shown in Fig. 5 of the drawings.

The clutch D is of the ordinary form of construction. The inner member, A, is feathered onto the horizontal shaft b, so as to permit of a slight longitudinal movement, while the other member, A is rigidly attached to the band-pulley D and revolves loosely with the same on the shaft when the mechanism is thrown out of engagement and the machine proper is at rest. That part of the clutch recessed for the reception of the counterpart is provided with an annular groove, into which fits the projecting bearings (0 attached to the inside of the yoke ed, as shown in Fig. 7 of the drawings. By this arrangement the clutch is arms cl between the dies.

2 ascent thrown in or out ot'engagement by a corresponding movement of the opposite end of the shifting-lever D.

On one end of -the horizontal shaft B is the trip-cam D which is brought in contact with the projection G on the collar 0 at each revolution, thereby throwingthe mechanism out of gear. One end of the horizontal spring I) is connected to the projecting arm of the collar C while the opposite end is attached to the bracket 1), secured to the back part of the frame-work, as shown in Fig. 5 of the drawings.

The operating-lever B is placed upon the cam-rod E, and has connection with the crankarm E, located on the cam-rod E", by means of the connecting-bar E These cam-rods pass through the frame-work near the top and just immediately above the die-plate D. As the operating-lever B is depressed to throw the machine into operation the cam-rods rotate far enough to bring the cam-projections F in contact with the upper side of the dieplate D ,-forcing the same down to its proper position to be operated against by thelower (lies. \Vhen the mechanism is thrown out of gear the die or crown plate D is returned to its normal position through the medium of the flat spring F, the ends of which rest upon the top of the framework, and the'middle having connection with the center of the die-plate by means of the book 01 and the eyebolt cl.

At the back side of the machine, as shown in Fig. 5 of the drawings, is placed the rockshaft F one end of which is bent at right angles to form the upwardly-projecting arm (1 Attached to this rock-shaft at a point equidistant from the ends are the two circular arms d which take a downward course and have V-shaped notches in the ends. These arms pass in between the upper and lower dies or formers at each revolution of the machine and force out the corrugated sheet of metal, so that it may be conveniently removed. This operation is antom aticallyperformed by means of the crank-arm E striking the upper end of the arm 0'! as the mechanism is thrown out of gear, rotating the rock-shaft, and'throwin g the The end of the rockshaft bent upward to form the arm 01 will be so weighted as to return the rock-shaft to its normal position by force of gravity when released from contact with the crank-arm E. Force is given to the blow of the crank-arm E and the mechanism assisted to return to a normal position by the vertical spiral spring F one end of which is connected to the crank-arm E and the other end to the frame-work A.

Motion is imparted to the roller or shaft B by means of the pinion H, located on the opposite end of the shaft 1) from the clutch-box D, which engages with the gear-wheel H, located on the shaft B.-

The operation is as follows: Fig. 1 of the drawings shows the mechanism outof gear. It will be noticed that the forward or straight in Fig. 2 of the drawings the inner end of the lever comes in contact with the under side of the jaw a which has the effect of raising the shaft B just high enough to allow the cam D to pass under the projecting arm 0 at the same time the horizontal spring b imparts a slight lateral outward movement to the vertical shaft 13, which brings the jaw a underthe inner end of the operating-lever. The same movement throws outward the end of the lever D by means of the arm 0*, connecting the end of said lever and the projection C, which has the efiect of throwing the clutch into gear by means of the yoke end of the lever D. When the sh aft or roller B completes a revolution the tripping-cam D strikes against the projection 0 imparting a lateral inward movement to the shaft B, throwing the clutch out of engagement, and releases the inner end of the operating-lever from'between the jaws to and a Having thus described my invention, what I claim as new,,and desire to secure by Letters Patent, is-
